06-16-2016, 06:10 PMHi I have a Sinnis Apache 125 (QM125GY) I currently have 16T Front sprocket and a 51T Rear Sprocket and I can get to 60MPH at a push (65 with wind pushing me along 😂)
Modifications I also have:
- Cone Air Filter
- DEP Exhaust Header Pipe
- Carbon Stubby Slip On End Can (No DB killer)
- 95 Main Jet
I'm trying to find a 17T front sprocket to help the bike a bit more at high RPM/Top speed but can't find one anywhere if anyone knows where I can get one I'd much appreciate it.
Also it's currently running rich (fuel smell from exhaust, black spark plug) does anyone know how to solve this
Also any extra tips on how I can improve performance would be gratefully appreciated
Thanks in advance

Smaller REAR sprocket is easier to get...

JT don't had 17T in this model... Some small chinese maker had 17T w/ C45 steel which longevity is a BIG ? https://item.taobao.com/item.htm?id=42309669041
